Embodiment Construction

[0032] Take the three-dimensional real-time thermal field distribution of multi-antenna combination microwave interventional therapy for liver cancer as an example.

[0033] First, measure and calculate the real-time three-dimensional coagulation thermal field distribution of a single radiation electrode under different radiation powers through the combined equation;

[0034]The monopole microwave radiation pre-experiment on the isolated pig liver shows that the monopole implanted microwave antenna is symmetrically distributed in the r direction and theta direction, so the SAR solution can be treated as a two-dimensional problem. Based on this, the analog measuring device of Fig. 1 is designed, and the center of the flat plexiglass plate with a thickness of 1.5 cm, 15×15 cm square, and flat is hollowed out to form a frame 20 with a peripheral width of 1.5 cm. D=15.1cm, high 20cm are used as in the plexiglass cylinder barrel 21 of support cover, adopt plexiglass because this ki...

Abstract

The combined multiple-antenna and heat field method for microwave intervention treatment of tumor includes the following steps. In the first step, the real-time 3D solidification heat field distribution of single antenna under different radiation power is obtained via measurement and calculation. In the second step, 3D solidification heat field distribution data base is found out for two or more antennas via permutation and combination to establish computer model and analysis with the limited element software based on the conditions of antennas, power, time of different power and blood stream perfusion rate of cancerized tissue. In the third step, the temperature boundary condition for the treatment after being 3D reconstructed is added into the heat field distribution data base in different conditions to form in the computer real-time heat field distribution data and corresponding 3D solidification heat field illustration under the different condition parameters.

Description

Technical field: [0001] The invention belongs to the combination method of multi-antenna microwave radiation heat field, in particular to the combination method of multi-antenna microwave interventional treatment of tumor coagulation heat field. Background technique: [0002] The technology of combining multi-antenna microwaves to form a large coagulation thermal field first appeared in 1999, when it was a case of dual antennas (known as double guides in this industry); in 2000-2001, three antennas (known as three guides by custom) appeared. And the case of four antennas (customarily called four guides). However, the real-time three-dimensional distribution of the combined thermal field under the multi-antenna condition has not been obtained, so it cannot be applied clinically, so it is limited to experimental research. Invention content: [0003] The present invention overcomes the technical defect that the real-time three-dimensional distribution of the combined coagula...
